Which solution will meet these requirements in the MOST operationally efficient way?
A. Create an Amazon SQS FIFO queue. Configure the microservices to use the SQS queue to exchange messages.
B. Use Amazon SNS topics to connect the microservices to one another. Subscribe the microservices to the SNS topics. Use the Amazon SNS API to send and receive notifications between microservices.
